Application filed. October 18, 1926. "Serial 'No. 142,475.

My invention relates to improvements in pump rod hanger mechanism. It relates particularly to mechanisms for supporting on a walking beam a pump'rod supporting rope. i

One of the objects of my invention is to provide a novel hanger mechanism of the kind described, which is simple, cheap, durable, strong, not liable to get out of order, which can be readily applied to pumping mechanisms in common use, and which will reduce to a minimum the wear upon the rope and the bending of the pump rod.

A further object of my invention is to provide a novel yoke adapted to be seated on a walking beam and to support the rope in a manner such that the latter will not be subject to kinking and undue wear when the beam is oscillated.

My invention provides still further novel means for adjusting the rope guiding mechanism to different operative positions on the walking beam.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings, which illustrate the preferred embodiment of my invention,

Fig. 1 is a side elevation of my improved hanger mechanism shown mounted on a portion of a walking beam.

Fig. 2 is an end elevation of the same.

Fig. 3 is a top view of the same.

Fig. 4 is an enlarged section on the line H of Fig. 1.

Fig. 5 is a section on the line 5-5 of Fig. 4.

Fig. 6 is a section on the line 66 of Fig. 1. i

Fig. 7 is an enlarged longitudinal section of one of the bearings for the braces on the walking beam and parts connected therewith.

Fig. 8 is a side elevation of what is shown in Fig. 7.

Fig. 9 is a perspective view, reduced, of the mechanism shown in Fig. 1.

Similar reference characters designate similar parts in the different views.

1 designates a walking beam, such as is commonly used in oil or gas 'well pumping structures, pivoted on a horizontal shaft 2 mounted on a pedestal 3, a part of which is shown.

4 designates the usual pumping or polish rod to which are attached, in any usual manner, as by a clamping device 5, the end portIOIIS'Of a rope or wire cable 6.

Forfsupporting the rope '6, Iprovide a yoke 7', the under side of which has a cylin- The upper'side of the yoke 7' isprovided I with an inverted U-shaped arcuate groove 10, which serves as a seat in which the'rope 6 is mounted. When the beam 1 is oscillated on the shaft 3, the yoke 7 will oscillate with the rope 6, sothat the latter will not kink or be sharply bent. I Y

The yoke 7 is adapted to be used in connection with two arcuate guiding members 11 having guiding channels 12 for receiving and guiding therope 6. The members 11 are pivoted at their upper end portions, independently of the pivoting of the yoke 7,

on a transverse bolt 13 disposed in the beam 1 so that the rope 6 will pass tangentially to the yoke, the latter swinging to accommodate the position of the rope .and to have its seat 10 aline with the channels 12.

To adjust and hold the guiding members 11 in different operative positions, with relation to the axis of the walking beam 1, so

as to obtain a proper tangential relationship of the rope 6 with relation'to the guiding members, and by which the lower ends of the members 11 may be adjusted toward and from the axis of the beam 1, there are provided two bars 14, which are respectively pivoted to the members 11 adjacent to the lower ends thereof, and which respectively are longitudinally adjustable in two channel plates 15, secured respectively to opposite sides of the beam 1.

Each bar 14: is threaded and has mounted on it at opposite ends of the adjacent channel plate 15, two nuts 16 which bear against washers 17 on the bar and which bear against the ends of the plate 15. By. adjusting the nuts 16, the bars 1 1 can be made to adjustthe lower ends of the guiding members 11 to different operative positions and to different distances from the axis of the beam 1.

lVhen used with the guiding members 11, the yoke 7 will swing on the beam 1 to prop erly guide the rope 6.

I do not limit my invention to the structure shown and described, as many modifications, within the scope of the appended i s; may be made flieut lepati yam the spiiiitoi my 'iilVfintion,
